"A harrowing first-person account by a low-time instrument pilot who was flying home IFR at night with his wife in their Piper Tri-Pacer when he ran into a nightmare: severe icing due to an encounter with unforecast freezing rain. If you fly light planes in IMC during the winter, this story will send chills up your spine."

I'd been cleared to 7,000 and instructed to contact Center upon reaching
that altitude
Center responded :
Oh boy, not those fateful words! I thought for a moment. Was I really going
to say the E-word? Was I?
It was barely one week after getting my instrument rating, my first real
IMC cross country, and my wife's first IFR experience...and things were not
going well.
Just then a severe engine vibration started. I mean so sever I thought the
engine might rip off its mounts (if it hadn't already). I immediately pulled
back on the power and dropped the nose.
Again Center responded:
What I wanted to say was "What more does it take!" But this wasn't the time
for witty rejoinder.
We were iced up bad, real bad. I fought to look away from the panel to see
what was almost three-quarters of a inch of clear ice glued to the front
half of the wing struts. It was in three distinct layers, each about a quarter
of an inch thick. The lower layers adhered further back than the top layer.
I looked at the pitot tube and saw a one-inch ball of ice stuck to the end.
It looked like a horizontal lollipop. No pitot heat in this Tri-Pacer, either.
The ice covered the bottom of the wing, making it look as smooth as a well
sanded composite. All the details were gone -- inspection plate covers, flap
hinges, screw heads -- all concealed under the ice blanket.
I keyed the mike to say the words that I had feared to say. What the hell,
I thought -- if I get out of this one, I'll gladly deal with the FAA!
How'd I get into this mess? Our earlier 125 mile flight from the Blaine Airport
in Minnesota northwest to Park Rapids -- to have dinner with relatives --
had been uneventful as we flew through and on top of a cloud deck of about
5,000 MSL and landed Park Rapids IFR without incident.
After an early dinner, we planned to depart for home at 6 p.m. Cloud bases
then were 1,200 feet and the only significant issue was the possibility of
icing climbing through 6,000 MSL to our cruising altitude of 7,000 MSL on top. (tops 5,000)
Pilot reports said negative icing from PR south and a trace was reported 70
miles north by a C-180 on decent. After departing PR and climbing to 4,000 I asked
my wife, Gail, to look for icing on the struts and tires as I had noticed
a several degree drop in OAT to just about 0C. She replied that she didn't
see anything. I checked out my window and saw nothing that would indicate
any icing conditions.
Two minutes later, all hell broke loose...
As we climbed out of 4,500 it was becoming obvious that we were nearing the
tops of the clouds. An occasional whisper of lighter skies encouraged me
that we'd soon be on top and I'd be able to relax a little as I was nervous
as hell. The air was bumpy and I was working up a sweat.
I knew my experience level. As an IFR pilot for all of one week, I was as
green as they come. But even I knew something wasn't right with this picture.
Airspeed read 90, attitude indicator showed us pitched for a climb, but the
VSI was showing no climb, and maybe even a little descent.
"Scan, scan, scan. What's wrong?" I asked myself. Why aren't we climbing?
I checked everything: carb heat, engine instruments, flaps up, throttle and
RPM okay. Everything checked out. Damn, must be ice. Need to get out of the
clouds, need to get just a little higher.
I released just a small amount of back pressure from the yoke and then pulled
back to a best rate of climb pitch. Almost on top! I can see it! 5,000 feet,
blue sky with just whispers of cloud above us. Almost there! Almost...
Suddenly, the altimeter started to drop and the vertical indicator slumped
to about 700 FPM decent. Oh *$%#! The airspeed still read 90. That can't
be! This airplane doesn't stall at this airspeed or in this attitude.
By this time Gail had become nervous as I had been talking out loud about
getting on top. Having picked up that it was the ice that was keeping us
from climbing, she looked understandably concerned.
I dropped the nose and released pressure on the yoke. I cranked in a couple
of turns of down trim to reduce the pitch angle. I wasn't going to let this
puppy stall again with the airspeed indicator inop.
That's when I called Minneapolis Center and said the E-word.
Like I really cared about the winds and temperature at the airport right
now.
OK, how do I get back to PR? I'm 25 miles out, power gone and iced up. I knew
I was scared. Center knew I was scared. Gail knew I was scared. I was really
getting scared.
I felt like I was starting to loose it. Overload: confusion, fear, lost...
But at the same time, I realized the only one who could help me was me. It
was all up to me to get us out of this. All the stuff I was supposed to have
learned in IFR training was going to have to pay off now...in spades.
The plane felt like a lead sled. After several attempts to bring the power
back up, I must have thrown the ice off the prop, because now it would
throttle-up smoothly. Finally some good news. Full power.
My highest priority task was now clear: to find a pitch attitude that would
keep the plane flying and stop my descent...or at least reduce it. The ASI
was still frozen at 90, so I used "feel" and the attitude indicator to find
the best pitch. With full power and a 300 FPM descent I could stay just above
what felt like an impending stall . This seemed like the best compromise
available.
Next task: I knew I had to turn around. But to what heading? I'd become
completely disoriented as to assigned headings, so I couldn't remember a
course reversal number to work with.
Center radioed they had put a airliner in a hold overhead as they would loose
radio contact with me as I descended. I changed frequencies as requested
and they asked for periodic updates on my situation. A call from the airline
pilot came next saying he was overhead and would stay with me. Right after
that Center reported they could no longer receive me clearly and for me to
relay through the airliner.
For a short period of time, I felt lost. Confusion and panic were starting
to set in and I started to think we wouldn't make it. I was worried throughout
the whole ordeal that maybe the vibration wasn't prop ice after all...maybe
something was coming apart in the engine, maybe it would go to hell again.
"Fly the plane, fly the plane," I kept hearing this voice in my head. Actually
it was many voices, the voices of all the instructors and other pilots I'd
flown with who over the years had said a thousand times "when your in trouble - first fly the plane!".
So I did.
I requested the airliner ask center for a reverse heading to fly back to
PR. I said I was disoriented and had made several turns off-course since
things went bad. Center said that I was below their radar coverage and they
couldn't give me vectors, but they advised that if I was still on my previous
outbound course, a heading of 300 would get me back.
I'm not sure if it was the turbulence or the situation -- or maybe it was
me -- but it seemed harder and harder to control the airplane. I struggled
trying to stay straight and level, but wasn't doing a very good job of it.
I was overcontrolling badly, banking 30 degrees left, than right. I've never
flown this badly, I thought. I better start flying better or we're not going
to make it.
My wife bumped my shoulder to get my attention and asked very seriously "are
we going to be all right?" I didn't know. I told her that I thought so but
to be honest, I didn't know. "Your lips are saying you think so;" she said,
"but, your knees are saying were screwed." Gail doesn't miss much. My legs
were shaking badly and I had not realized it before.
Then the airliner radioed that Minneapolis had requested "say souls onboard".
It was a real hard thing to key the mike. "Tell Minneapolis that zero seven
papa has two very scared souls on board," I responded. What else could I
say? It was the purest truth I'd ever spoken.
When Center asked for souls on board, that was a real turning point for me,
A reality check on my mental condition. I knew then that not many people
get asked that question and have the opportunity to talk about it later.
This wasn't a practice approach. I couldn't flip up the hood and say "damn."
No missed approach on this one.
I had to fly better than I had ever flown before. I had to think better and
faster than ever before. I had to get it right this time or we were going
to die. I wasn't about to kill my wife and myself and leave our children
orphaned. I could feel the adrenaline coursing through my system. It was
like the last second before I go out the door on a skydive, just do it.
I started the turn inbound but lost it as the left wing and nose dropped,
the airplane wouldn't respond to my control inputs to roll level and pull
up. Vertical speed was over 1,000 FPM down. I knew a spin had started
as the DG began to spin quickly to the right. I pulled the power, dropped the
nose, kicked opposite rudder, and held it until the DG stopped spinning.
I held the nose down for a period of time I thought would be adequate, and
then pulled back after leveling the wings and added power again. Buy the sound
of the air going past the cabin I could tell we got going pretty fast but we
slowed down quickly also. The attitude Indicator came
back to normal and I pitched and powered back again to best rate of "descent"
as it were.
I thought about the recent articles I'd read about spin training not being
necessary. Right, good plan!
A glance back to the DG reminded me that I had again forgotten the heading
to fly. I took a deep breath and decided to reprogram the VFR GPS I had with
us. It was originally set for Blaine and under normal circumstances would
have been my primary reference for a return heading but I wasn't thinking
as clearly as I normally was when I was just out shooting approaches.
I punched the "nearest airport" button and - Bingo! Heading 305. Why didn't I do that
a long time ago? Dummy...
Frequently I told the airline captain what was going on. It felt good to
have someone to talk to who would understand what I was saying and possibly
what I was going through.
The GPS gave me a heading of 305 but when I made a very shallow turn to that
heading on the DG, it became obvious that the DG had precessed a lot (or
tumbled) during that little spin episode. To avoid another situation like
the last, I turned slowly -- mostly with rudder and very shallow -- to a
GPS course that agreed with the GPS heading to PR. Slowly we kept descending
through the gray murky swirls of thick clouds.
We're finally heading in the right direction, but we still have a long way
to go, I thought to myself.
Scared, sweating, and angry with myself for putting my wife helplessly into
this situation, I sat there balancing the pitch with the "feel" of the airplane
hoping I could milk out the altitude we would need to get us back to the
runway.
At first I thought that all I could do was stay on course and wait. Then
I remembered one more thing my CFII once told me: if you run out of things
to do, you're forgetting to do something! So I kept scanning, double-checking
everything, pre-landing checklist - good idea! I started working on options, thinking
about what was coming up next. Trying to get back to one step ahead of it.
I'm a experienced skydiver and my wife has made one jump herself. While we
waited to break out of the clouds, I thought about how stupid it was for
us to ride this 42 year old fuel tank into the trees or swamp below when
-- if we had had chutes -- we could have just jumped and been assured of
our lives. I've made hundreds of jumps, and I was starting to have doubts
we were going to make it back to the airport. No fear, no questions, no regrets,
Just open the door and jump.... Screw the plane, I thought, that's what insurance
is for.
No chutes on board... Fly the plane.
It seemed like two hours -- actually about six minutes -- before we reached
the bottom of the cloud deck. We broke out of the clouds at 1,100 feet AGL
but were still unable to maintain altitude. Airspeed now read zero. Not that
it mattered; I wasn't going to believe the ASI no matter what it said at
this point.
The windshield and side windows were iced over and we could only see directly
left, right or behind, and nothing forward. I'd landed once before using
the GPS to align to the runway so I thought I could do it again. That gave
me some confidence, and I needed all that I could get.
When we went below 600 feet Gail and I looked desperately for a place to
set down, I had told her we might want to take our chances on a road or field
as we were getting down pretty low and I didn't think we'd make the runway,.
But there wasn't anywhere else to go. No roads or fields, just trees and
swamp. Our decent rate was down to about 200 FPM or less now, and seemed
to be getting better. Unfortunately the visibility was only just over a mile
so our ability to see possible landing sites was limited. I knew I had to
keep on the GPS course to the runway. I couldn't turn away just because I
thought I saw something.
Center relayed through the airliner a request for what approach I wanted.
This struck me as funny. Here we are, about 400 AGL without
a VOR signal, 8 miles GPS from the airport and they want to know what approach?
The airliner relayed Center's reply:
Great, just what I needed: towers! Makes the prospect of missing the airport
even more of a treat, I thought to myself.
Things started getting better. Three miles out I was able to climb some as
the ice was coming off a little at a time. A three-inch hole had started
to defrost near the bottom center of the windshield. I got up to about 500
feet AGL but decided to increase airspeed rather than altitude for the remaining
few miles. We had been riding at just over minimum controllable airspeed
for a long time and I felt better going just a little bit faster.
The GPS did its job, again, and we soon were dropping down to the runway.
The GPS showed a 100-knot ground speed over the threshold and I still had
power at 100%.
When only a couple of feet above the runway I pulled power back just a little
and pulled back on the yoke enough to maintain flight. Wrong, the plane stalled
and hit the runway like a ton of bricks. I had taken the precaution of asking
my wife to put her coat over her face and fold her arms to protect her head.
I didn't think I would be able to control the overweight skinny legged milk
stool at that speed, but I was wrong about that, too.
I braked hard. I couldn't see much out the little hole defrosted on the
windshield so I wanted to stop real bad. Then...we were stopped. On the center
of the runway. In one piece!
Large sheets of ice were falling off the bottom of the wings and crashing
into pieces that scattered down the runway. I turned around to see fire trucks
and police cars waiting with all their lights on sitting on the ramp. I had
not noticed them before, They were not in my three-inch view path, I guess.
Hey! We made it!!
I thanked the pilots of the holding airliner, and I meant it. I don't know
if they were trying intentionally to be calming or assuring, but they were.
The Center controller had been cool and professional, sympathetic to my situation
and impressively quick in putting the airliner overhead to keep me in
communication. I thanked him also. When the airliner relayed we were down
and okay, you could hear the relief in everyone's voices. Mine too.
And I thank my wife who, after helping to bust the remaining ice off the
airplane, was brave enough to get back in and fly back with me when I really
needed someone to fly with.
"Unforecasted freezing rain" said the FAA inspector investigating the incident
about a month later. I'm okay with that, there was no way I could tell it
was freezing rain at the time. I felt particularly good about the "unforecasted"
part -- at least the Feds didn't have known icing to hang my ticket on. In
any case, I promised they'd never hear the words "Rick", "Wagner" and "Ice"
in the same sentence again, and they were okay with that.
I guess you could say I learned a lot from that one.
Rick Wagner is a computer consultant who lives 30 miles north of Minneapolis
with his wife Gail and his three daughters Anne, Alice and Emily. Rick and
Gail own a restored 1954 Piper PA-22-135 Tri-Pacer N1507P. Rick is a private,
instrument-rated pilot who has now logged over 500 hours. He's working on
his commercial and multiengine ratings. Rick is also a master skydiver with
over 500 jumps, including jumps from a Boeing 727, a hot air balloon, helicopters
and inverted biplanes.
There I was, 5,000 MSL (about 4,000 AGL) with my wife beside
me in our 1954 Piper Tri-Pacer. The problem was that I was at full throttle
and pitched for a standard climb, but we were descending..
TriPacer Zero Seven Papa is 25 miles off of Park Rapids at 5000 and cannot
maintain altitude, we're turning back.
07P are you declaring an emergency?
Zero Seven Papa has severe engine vibration, we're iced up badly and cannot
maintain altitude, I've pulled the power and have lost the airspeed indicator.
We're turning back to Park Rapids!
Roger 07P, understand you're turning back to Park Rapids. Are you declaring
an emergency?
Affirmative. Zero Seven Papa is declaring an emergency at this time.
Zero Seven Papa you are cleared direct to Park Rapids, altitude your
discretion at or above 3100, weather at Park Rapids blah blah blah...
Tell Center 07P is 400 AGL and has no forward visibility due to ice on
the windshield. We're going to align to the runway with GPS and hope we don't
hit anything.
07P climb to 3,100 as soon as possible to minimum IFR altitude, if able.
Be advised there are towers east and north of the airport
